Description

2-Ethyl-1,3-Butanediol is a versatile diol intermediate valued for its dual hydroxyl functionality and hydrophobic ethyl side chain. This chemical structure makes it a key building block for synthesizing high-performance polymers, plasticizers, and specialty solvents. Industries such as coatings, adhesives, and personal care utilize it to modify product properties like flexibility, viscosity, and moisture resistance.

Application

• Polymer & Resin Modification: Used as a monomer or chain extender in polyurethane and polyester resins to enhance flexibility and hydrolytic stability.
• Plasticizer Production: Serves as a precursor for ester-based plasticizers, improving the low-temperature performance of PVC and other polymers.
• Specialty Solvents & Coupling Agents: Functions as a high-boiling, low-volatility solvent in coatings, inks, and cleaning formulations.
• Personal Care & Cosmetics: Employed as a humectant and viscosity modifier in lotions, creams, and hair care products.
• Chemical Synthesis Intermediate: A valuable starting material for producing pharmaceuticals, agrochemicals, and other fine chemicals.
• Lubricant & Functional Fluid Additive: Imparts moisture displacement and corrosion inhibition properties in synthetic lubricants and hydraulic fluids.
